Never drive interstate
You only see rear doors of semi trucks and truck stops. See the world on two lane roads.

If you care to read more about the Interstate system, Wikipedia has an excellent section on it. Pretty interesting. President Eisenhower was instrumental in creating it, and required that one mile sections had to be absolutely straight every so often. That way, planes could land on them in time of war, since runways would be a good target for an enemy.
